Unfortunatly, there is no support for any HDMI/DP based HDA codecs in this driver. Therefore we try to filter out known devices (normally the PCI device on 00:03.00). This could also be done in the platform_drv's configuration by explicitly naming the BDF but for better or worse that will not work when using a wildcard class like HDAUDIO which is done in generic run scripts. Issue #1644.
This repository contains device drivers ported from OpenBSD. Audio ##### The audio driver is ported from OpenBSD 5.7 and includes support for Intel HD Audio as well as for Ensoniq AudioPCI (ES1370) compatible soundcards. The HDA driver works on real hardware and Virtualbox whereas the ES1370 driver is only used in Qemu. Usage ===== You have to prepare the contrib sources for this repository by executing _tool/ports/prepare_port dde_bsd_. Also you need to make sure to add the 'dde_bsd' repository to the REPOSITORIES variable in your 'etc/build.conf'. Example ======= The driver can be tested by executing the run script 'run/audio_out.run'. This example plays a sample file in a loop. The file format is header less two channel float 32 at 44100 Hz. You may use the 'sox' utility to create these audio files: ! sox -c 2 -r 44100 foo.wav foo.f32
